So I just downloaded autopano video 1.5 and think it looks great. I stitched together 6 videos using the GoPro settings, and also with a preset template .pano. Once the reference panorama has been created, I try to edit it in Giga to correct horizon etc. Giga opens, but no pano opens, I just get a black screen.

I then try to manually open the pano it has created in my folder, but there is nothing in it. What am I doing wrong?
